A Sudden Bounce

Whoa! My eyes snapped wide and my round body wobbled right up! No warm-up needed. I felt a sudden burst of energy and gave a quick sideways bounce. Thump! I bumped right against the cool, smooth wall of a big clear plastic jug sitting behind me. It let out a neat little plastic rattle. I can move! I spun slightly and settled right back on the dark surface, grinning big.
